From bc8a0fac8677f729ab17176023be1a2653e8b9c6 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 11 Jan 2024 18:17:45 +0200 Subject: wifi: mac80211: don't set bss_conf in parsing When parsing 6 GHz operation, don't set the bss_conf values. We only commit to that later in association, so move the code there. Also clear it later. While at it, handle IEEE80211_6GHZ_CTRL_REG_VLP_AP.
